This study finds that alcohol and pilot age impair radio communication during simulated flight. Young (mean age 25 years) and older (mean age 42 years) pilots flew in a light aircraft simulator during alcohol and placebo conditions. In the alcohol condition, pilots drank alcohol and flew after reaching 0.04% BAC, after reaching 0.10% BAC, and then 2, 4, 8, 24, and 48 h after they stopped drinking at 0.10% BAC. They flew at the same times in the placebo condition. Alcohol and age impaired communication-based and overall flying performance during and immediately after drinking. Most important, alcohol and age cumulatively impaired performance, since older pilots were more impaired by alcohol. Notably, performance was as impaired 2 h after reaching 0.10% BAC as it was at 0.10% BAC. Moreover, overall performance was impaired for 8 h after reaching 0.10% BAC.
本研究发现，在模拟飞行过程中，酒精和飞行员年龄会损害无线电通信。年轻（平均年龄25岁）和年长（平均年龄42岁）的飞行员在饮酒和服用安慰剂的情况下，在轻型飞机模拟器中飞行。在饮酒条件下，飞行员饮用酒精后，在达到0.04%的血液酒精浓度（BAC）后飞行，在达到0.10%的BAC后飞行，然后在他们在0.10%的BAC停止饮酒后2小时、4小时、8小时、24小时和48小时飞行。他们在服用安慰剂的情况下在相同时间飞行。饮酒期间及饮酒后立即饮酒和年龄损害了基于通信的飞行性能和整体飞行性能。最重要的是，酒精和年龄会累积损害性能，因为年长的飞行员受酒精的影响更大。值得注意的是，在达到0.10%的BAC后2小时，性能受损程度与在0.10%的BAC时相同。此外，在达到0.10%的BAC后8小时，整体性能受到损害。
